Tok – an easy-to-use application for peer-to-peer communication. We use end-to-end encryption technologies to secure your conversations. With TOK, you can send messages, photos, videos and files of any type without anyone else listening in. TOK’s goal is to make the world connect freely. It is forked from Antox and Antidote.

A phone number or an email address is not required to create your TOK account. Your personal information is not traceable to a phone number or email address. All communication is interfaced with a randomly generated alpha-numeric user ID.

All conversations are immediately encrypted from end to end during transmission.

TOK’s peer-to-peer communication platform has no central server. After end-to-end encryption, any third party, even TOK engineers, can’t access your conversations.

– 1v1 messages
– Audio
– Audio filtering
– Audio notifications
– Avatars
– Changing nospam
– Chat logs
– Contact aliases
– File transfer
